Title: Power or electric power generator
Inventor: NAKAJIMA HIROSHI
IPC: F03G3/00
Filed: 2001-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a power or electric power generator capable of eliminating inconvenience in the case of power transmission by a mechanical power transmission shaft. SOLUTION: When a force for rotating a power transmission shaft 30 is received from the outside, the rotating power causes an outer cylinder 20 to rotate around a vacuum thermal insulation vessel 15. The rotation causes a permanent magnet 21 to rotate around the vacuum thermal insulation vessel 15. The permanent magnet 21 is provided so as to face a superconducting bulk 5, so that magnetic coupling thereof transmits the rotational movement of the permanent magnet 21 to the superconducting bulk 5. Thus, a rotor 6 securing the superconducting bulk 5 rotates, and mechanical power transmitted from the outside permits power generation.  On the contrary, when the superconducting bulk 5 is rotated by energizing a superconducting coil 3, the magnetic coupling transmits the rotation to the permanent magnet 21 and permits the generation of the mechanical power through the power transmission shaft 30.

Title: Transmission controller for continuously variable transmission with infinite variable speed ratio
Inventor: NARITA YASUSHI
IPC: F16H61/10
Filed: 2001-09-07
Abstract: PROBLEM TO BE SOLVED: To prevent generation of mode changeover hunting to prevent drivability in mode changeover control between a direct connection mode and a power circulation mode. SOLUTION: In this controller, normal transmission control in the power circulation mode is executed along a variable speed line in an upshift from F1 to F5 accompanying a changeover from the power circulation mode to the direct connection mode, executed because of increase of a vehicle speed VSP in a full-closing state of a throttle opening TVO. The changeover to the direct connection mode is started from F2 toward F3 along a line γ1 by retention of a CVT variable speed ratio. After F4 wherein an IVT variable speed ratio becomes a high-speed side IVT limit variable speed ratio γ2, the normal transmission control in the direct connection mode is executed along the variable speed line to execute the shift from F4 to F5.  In a downshift followed by a direct connection mode to power circulation mode changeover from F5 to F1, a shift from F5 to F1 via F4, F6 and F2 is similarly performed to prevent the generation of the hunting in the mode changeover.
